Socal especially is notoriously horrendous when it comes to cops, their attitude, and disposition. Its not our fault everyone stepped on them in high school, but it becomes our problem. Sorry to hear that bro, when you get slapped with something like that you just feel helpless, it ****ing sucks. But try to get all the documentation that you can to build your case. The more evidence you have to provide the judge with, the stronger and more credible your case will seem, while the officer has only his word. Good luck dude.
